This Bose PS3-2-1 III speaker system is being sold as-is for parts or repair. While the system powers on and the treble speakers function correctly, the bass component is non-functional and emits a hum without driving any bass output. It worked recently, and I tested multiple cables, so I think the speaker isn't blown but rather that there's a connection issue. This issue may require attention from someone with experience in electronic repairs or could be used for parts to restore other systems. The overall physical condition is good, with no major cosmetic defects. This could be an excellent opportunity for enthusiasts and technicians looking to restore the unit's full functionality.
